Once the frequency of the phase AN or AB voltage (depending on wye or delta connection) is out of range of the overfre-
quency and underfrequency setpoints, a trip or alarm will occur.
This feature may be useful for load shedding applications on large motors. It could also be used to load shed an entire
feeder if the trip was assigned to an upstream breaker.
